Enterprise energy management system

Abstract

A system for managing energy consumption by equipment located at a site. The system includes a database including information relating to pieces of energy consuming equipment located at a site. A server is programmed to calculate an expected energy consumption profile and to notify a user if an actual energy consumption exceeds the expected energy consumption.

1. A system for managing energy consumption by equipment at a site, the system comprising:
 a first database including a plurality of characteristics relating to a piece of energy consuming equipment located at the site; 
 a second database including a plurality of service technicians; and 
 a server including software for determining an expected energy consumption profile, based on the plurality of characteristics relating to the equipment and the site environment; 
 wherein the server generates an alert, if an actual energy consumption exceeds the expected energy consumption, and 
 further wherein the server includes total cost software for calculating a total cost of a selected piece of equipment, based on a purchase cost, a repair cost, and an energy consumption cost. 
 
     
     
       2. The system of  claim 1  wherein the server further compares the actual energy consumption to refrigerant loss data. 
     
     
       3. The system of  claim 1  wherein the server generates a work order including the plurality of characteristics relating to the piece of energy consuming equipment. 
     
     
       4. A network-based system for managing energy consumption by equipment at a site, the system comprising:
 a first database including a plurality of characteristics relating to a piece of energy consuming equipment located at the site; 
 a second database including a plurality of service technicians; and 
 a server including software for determining an expected energy consumption profile, based on the plurality of characteristics relating to the equipment and the site environment; 
 wherein the server generates a service request, if an actual energy consumption exceeds the expected energy consumption, and 
 further wherein the server includes total cost software for calculating a total cost of a selected piece of equipment, based on a purchase cost, a repair cost, and an energy consumption cost. 
 
     
     
       5. A method of managing energy consumption by equipment located at a site, the method comprising:
 collecting a set of information relating to a plurality of pieces of energy consuming equipment located at the site 
 calculating an expected energy usage profile for the site, based on the information; 
 collecting actual energy consumption data on a periodic basis; 
 comparing the actual energy consumption data to the expected energy usage profile; and 
 triggering an alarm when the actual energy consumption data exceeds the energy usage profile; and 
 calculating a total cost of a selected piece of equipment, based on a purchase cost, a repair cost, and an energy consumption cost.
